Loose Diamonds

They say that diamonds are a girl's best friend! In addition to
being one of the world's most desirable gemstones, diamonds are also
the hardest naturally occurring substance known to man.
These valuable crystalline carbon minerals are formed deep in the earth
under intense pressures and very high temperatures. Diamonds are
mined from volcanic pipe deposits that are found primarily in southern
Africa and Siberia and to some extent Canada, Brazil and Australia.

Diamonds are also used for industrial applications. More than
three quarters of loose diamonds are used industrially, mainly as cutting,
grinding, and polishing tools. Diamond industrial tools are used on
such diverse materials as ferrous and non-ferrous metals, glass, and
ceramics as well as natural stone and concrete.

Loose diamonds may be transparent, translucent or opaque. Depending
on their characteristics and color, they are designated for use in jewelry
or for certain industrial applications. The highest grade diamonds
are used in jewelry, such as necklaces, rings, or earrings.

Gemstone diamonds
are judged by the four Cs: carat, clarity, color, and cut.
Gem diamonds are usually transparent and colorless, or have a yellow
hue. The most valuable diamonds are colorless or pale blue, and
have few "occlusions," or flaws, marring their clarity. Industrial
diamonds, while as hard as gemstone diamonds, are usually gray or brown.

Traditionally, women's engagement rings feature one large diamond and
perhaps two or more smaller diamonds. Wedding rings and wedding
bands sometimes feature one or more diamonds as well. Diamonds
can be cut in several different ways and shapes to refract the light
differently. They are then set in a choice of settings, depending
upon the wearer's preference.
